Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 1 g06035725Note: Ensure that there is no damage to the shank of connecting rod bolt (3) prior to the installation of heat shrink tube (10).Note: Ensure that the shanks of connecting rod bolts (3) are free of debris and oil prior to installation.Note: The connecting rod bolt (3) may be reused if bolt reuse guidelines in Reuse and salvage Guidelines, SEBF8301, "Inspection and Reuse of Critical Fasteners Used in All Engines" are met. An overloaded bolt can be detected by threading connecting rod nut (2) onto the bolt by hand. If the threads are not damaged, connecting rod nut (2) will easily reach the end of the bolt thread with light finger pressure. If connecting rod nut (2) stops before reaching the end, do not reuse the bolt.
If a new heat shrink tube needs to be installed, follow Step 1.a through Step 1.d.
Clean the shank of connecting rod bolt (3) free of debris and oil.
Slide the new heat shrink tube (10) onto connecting rod bolt (3). Install the new heat shrink tube (10) to Dimension (Y). Dimension (Y) is 1.50 mm (0.059 inch).
Use a suitable heat gun or use a suitable oven to shrink the heat shrink tube (10) onto connecting rod bolt (3). If a suitable oven is used, heat the connecting rod bolt (3) and heat shrink tube (10) at a temperature of 135° 14° C (275° 57°F) for 10 minutes.
After installation of the new heat shrink tube (10) onto connecting rod bolt (3), allow connecting rod bolt (3) to cool. Ensure that heat-shrink tube (10) does not have any bumps or wrinkles. Ensure the heat-shrink tube (10) does not move under light finger pressure.
Illustration 2 g03376355Note: Ensure that piston (4) is clean and meets reuse guidelines.
Before the piston rings are installed on the piston, check the end gap on each piston ring. Refer to Specifications, "Piston and Rings".
Do not install the piston rings without the use of the piston ring expander. Piston ring breakage and piston damage may result if the piston ring expander is not used.
Use Tooling (D) to install the piston rings
